Earnings Per Share Attributable to Federated Investors, Inc. Shareholders | (13) Earnings Per Share Attributable to Federated Investors, Inc. Shareholders The following table sets forth the computation of basic and diluted earnings per share for amounts attributable to Federated Investors, Inc. using the two-class method:
For the three- and nine-month periods ended September 30, 2011, 0.4 million and 0.9 million stock option awards, respectively, were outstanding but not included in the computation of diluted earnings per share for each period because the exercise price was greater than the average market price of Federated Class B common stock for each respective period. In the event the awards become dilutive, these shares would be included in the calculation of diluted earnings per share and would result in additional dilution. For the three- and nine-month periods ended September 30, 2010, 3.4 million and 2.9 million stock option awards, respectively, were outstanding but not included in the computation of diluted earnings per share for each period because the exercise price was greater than the average market price of Federated Class B common stock for each respective period. |
